Chemical Structure
Description
2-Cyano-3-(2,5-dimethoxyphenyl)-N-[3-(trifluoromethyl)phenyl]propanamide (CAS 1261005-96-2), molecular formula C19H17F3N2O3 and molecular weight 378.35 g/mol, is a CATO reference standard with documented purity and traceability.
2-Cyano-3-(2,5-dimethoxyphenyl)-N-[3-(trifluoromethyl)phenyl]propanamide (C19H17F3N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Cyano-3-(2,5-dimethoxyphenyl)-N-[3-(trifluoromethyl)phenyl]propanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
